COMPONENT MOUNTING MACHINE AND COMPONENT MOUNTING ASSEMBLY LINE

A component mounting machine (1) of the invention includes a frame (9); multiple component supply devices (3) which respectively include multiple component supply units (feeder units 8) and are exchangeably equipped; a component transfer device (4) in which a reference height (H0) as a reference of a lifting and lowering operation of a mounting nozzle (suction nozzle 46) is set; a height memory section (device control section 38) which memorizes a height unique value that is unique for each component supply device and that is a height unique value (Heg) based on unit heights (HL, HC, and HR) of each component supply unit when the component supply device is equipped; and a height correction control section (control device 6) which corrects a lowering operation stroke amount of the mounting nozzle based on the height unique value of the equipped component supply device. According to this, an error in a height direction can be comprehensively absorbed and the component can be stably picked up by controlling a component pick-up operation of the mounting nozzle based on the height unique value.
